BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention generally relates to office exercise devices that can be used by a user while seated at a desk, and in particular, to a hand and foot lever-arm rowing type exercise device that is mounted in the foot space under a desk.

2. Description of the Prior Art

Many people appreciate the need to exercise regularly. Unfortunately, busy business schedules often make it difficult to incorporate a regular exercise schedule into a working week. An exercise device that can be used while a person is working would provide the benefit of exercise that can be achieved during working hours.

U.S. Pat. No. 5,807,211, issued Sep. 15, 1998 to Berryhill, shows an exercise device that is particularly adapted for use by individuals while seated in a stationary chair. The inventive exercise device employs a folding frame, which has attached bicycle type pedals, a leg press bar, and resistance pulls. The bicycle type pedals are attached to one side of the folding frame, the leg press bar hangs from a horizontal bar on the opposite side of the folding frame, and the resistance pulls are also attached to the other side of the folding frame, opposite the bicycle type pedals. By positioning the front of the exercise device in front of an individual seated in a chair, pedaling exercises can be accomplished.

U.S. patent application No. 20020137606, published Sep. 26, 2002 by Willis, puts forth a portable leg or arm powered exercise device for a person that may include a seating pad permanently or detachably affixed to a support base upon which one or more resistance members are mounted for engagement by one or both feet or hands of the user. Preferably the resistance members include coil springs to provide the resistance and spring control guides to prevent overly sharp angular bending of the coil springs. The exercise device can be used while seated with the device placed under a desk or table having limited vertical dimensions.

U.S. patent application No. 20020142898, published Oct. 3, 2002 by Willis, concerns an office chair and office desk independently incorporating certain activity features. The chair and desk arrangements allow the user to perform beneficial exercise without leaving the chair or desk by utilizing movable exercise arms attached to adjustable variable resistance bearing assemblies attached to the chair seat or the desk to provide a full range of omni-directional exercises.

U.S. Pat. No. 5,807,212, issued Sep. 15, 1998 to Nelson, concerns a leg exerciser that includes a leg exercise device sized to fit beneath the desk of a user, and an anchoring device attached to the exercise device. The anchoring device is adapted to be affixed to the user's chair. This allows the user to sit at his or her desk in the chair and actuate the leg exerciser while doing so.

U.S. Pat. No. 6,261,212, issued Jul. 17, 2001 to Vallone, provides an adjustable resistance rehabilitation exercise device for use by individuals without supervision to follow prescribed or desired iterative cycles of therapeutic exercise regimens. The adjustable resistance rehabilitation exercise device preferably includes a pilot pulley assembly and a adjustable resistance control spooler assembly, mounted and secured to individual ‘O’ clamp and/or channeled ‘U’ clamp assemblies, interconnected by a flexible cord, with bayonet clips secured at both ends of the cord, and supplemented with hand grips, precision straight scale, multi-purpose harness assembly and anchoring device. The ‘O’ clamp and channeled ‘U’ clamp screw assemblies may be disassembled and employed in either of two ‘O’ clamp screw holes and also are interchangeable between the ‘O’ and Channeled ‘U’ clamps. The pilot pulley assembly is configured with a single grooved roller and performs the primary function of establishing and maintaining a tangential path for the flexible cord travel from the adjustable resistance control spooler assembly to the pilot pulley roller to minimize friction and resultant added exercise forces. The adjustable resistance rehabilitation exercise device accessories include hand grip(s) and a precision, spring style, straight scale for calibrating and verifying prescribed and preset exercise forces for individual therapeutic regimens. The channeled ‘U’ clamp is more ideally suited for attachment to flat board surfaces such as found in physical therapy plinths, tables, desks and exercise/work bench configurations.

U.S. Pat. No. 4,482,149, issued Nov. 13, 1984 to Weldon, discloses an arm exercise device that has an exercising arm adjustable to different lengths to accommodate forearms of different lengths and attached to a bearing-supported lateral rod which has an upright portion at the other end. Springs or other tension devices are attached at one end to the lateral rod and, at the other end, to a tension bar that is adjustable with respect to the base. In one variation, the tension arm can be re-positioned 180 degrees from its initial position, thereby permitting use of the device for exercising right or left arms. In a further refinement, safety stops are provided which limit the movement of the exercising arm, thereby preventing it from passing the upright position. The base of the exercise machine is held in place on a table or desk by table clamp braces.

U.S. Pat. No. 5,160,303, issued Nov. 3, 1992 to Smith, indicates a compact and easily adjusted exercising device useful for exercising the upper arms, shoulders, calves or the like. The device has a base that may be supported on a desk, table or floor. A pair of uprights support an upper bar over which one or more rubber bands are placed. This bar is removable when it is desired to change the rubber bands. A hollow lower bar is held between the uprights and the one or more rubber bands pass over this bar. A handle-supporting bar is then slid through vertical slots in the uprights and through the center of the lower supporting bar. This provides a light, easily adjusted exercising device that can be easily used by the busy executive or even by bedridden persons.

U.S. Pat. No. 5,044,633, issued Sep. 3, 1991 to Rice, provides chair that functions well as an ordinary office chair and which can be used to perform exercises. The chair includes all the attributes of a comfortable office chair, including a padded seat with a seat bottom and seat back, and a pedestal with casters that rollably support the seat on a chair pad lying behind an office desk. The seat back has an upper part with extendable handles that can be grasped to raise and lower it while a mechanism resists vertical movement to provide exercise. The seat has armrests that each have a moveable portion with extendable handles and a resistance mechanism to provide exercise in raising and lowering the armrests. The chair also has an extendable mechanism mounted under the seat bottom and having a pair of foot handles that allow the seated person to move the handles forward and back for further exercise. All exercise mechanisms of the chair can be deployed, used, and stowed while the person remains seated, so the person is encouraged to conduct exercises during brief appropriate periods such as when the person is talking on a speakerphone.

U.S. Pat. No. 3,738,649, issued Jun. 12, 1973 to Miller, discloses an exercising arrangement that includes a chair with a space beneath the seat portion. The exercise devices are mounted on a platform beneath the seat and concealed by front and side panels. A track comprises the mount for the platform, permitting it to be extended in front of the seat portion where the exercise apparatus is accessible for manipulation by a person sitting in the chair.

U.S. Pat. No. 5,833,575, issued Nov. 10, 1998 to Holslag, illustrates a portable exercise apparatus that includes a support frame, which has a base mountable under a chair to hold the base in a stationary position with a user seated on the chair and an upright standard mounted upon the base. The apparatus also comprises a shaft mounted to an upper end of the upright standard and that has opposite ends extending from opposite sides thereof. The apparatus further comprises a pair of arms disposed on opposite sides of the upright standard with each arm at one end mounted to one end of the shaft for rotatably mounting the arm to the upright standard. The apparatus includes a pair of pedals each mounted to the other end of each of the arms for engagement by a user to create the force necessary to rotate the arms relative to the upright standard. The apparatus also includes a resistance generating and adjusting mechanism disposed on the ends of the shaft at the opposite sides of the upright standard and engaged with the one ends of the arms and being operable to generate and selectively adjust a level of resistance to rotation of the pair of arms relative to the upright standard in response to rotation of the arms. The resistance generating and adjusting mechanism includes at least one conical-shaped spring washer received over one of the shaft ends and being respectively compressible and expandable for correspondingly increasing and decreasing the level of resistance to rotation of the arms by the user. The support frame is attachable to a desk chair or the like.

U.S. Pat. No. 5,314,392, issued May 24, 1994 to Hawkins, illustrates a pedal exerciser for performing stepper exercises. The device includes a pair of pedal cranks, each crank driving one of a pair of crankshafts that are coupled together by bevel gears such that, when one pedal is forced to rotate downward, the other pedal rises thereby providing reciprocating stair climbing motion. Adjustable resistance to stepping is provided by a resistance pad against either the idler bevel gear or one or both crankshafts. The compact construction is amenable to positioning the exerciser under a desk or table for a seated user. A detachable frame with handles may be attached for an erect user.

U.S. Pat. No. 3,751,033, issued Aug. 7, 1973 to Rosenthal, indicates a combination of a chair and an advanceable and retractable pedaling device. The pedaling device is pivotally secured to the bottom of a chair by a telescoping member. The telescoping member with the pedaling device may be adjusted to a desired angle for comfortable pedaling. The length of the telescoping member may be adjusted to suit the length of the user's legs. An adjustable counter-force device is provided to vary the force desired applied by the user. The device may be locked in place out of the way, under the chair.

While there have been a number of portable exercise devices and exercise devices attachable to furniture, none provide a lever-arm rowing type exerciser attached under a desk. The present invention addresses the inadequacies of the prior art by providing a simplified exercise device for use while seated in a chair. The exercise device of the present invention is small, lightweight and easily secured to any desk or cubicle. In addition, due to its relatively small size and lightweight the exercise device of present invention is easily stored.
